1. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?
- A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
- B. Administer a retention enema of Kayexalate.
- C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
- D. Administer a lidocaine bolus IV push.
Correct answer: B
Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.
2. A client diagnosed with tuberculosis (TB) is placed on drug therapy with rifampin (Rifadin). The client should be instructed to report which effect(s) of the medication to the healthcare provider?
- A. Reddish-orange discoloration of body fluids
- B. Bloody or blood-tinged urine
- C. Blurring of vision
- D. Weight gain of more than 2 pounds in a week
Correct answer: A
Rationale: The correct answer is A. Rifampin (Rifadin) commonly causes a reddish-orange discoloration of body fluids, including urine, sweat, saliva, and tears. This is a harmless side effect but should be reported to the healthcare provider for monitoring. Choices B, C, and D are not typically associated with rifampin therapy. Bloody or blood-tinged urine may indicate other issues such as urinary tract infection or kidney problems, blurring of vision may suggest eye problems, and significant weight gain could be related to various health conditions unrelated to rifampin.
3. The healthcare provider is caring for a client with jaundice. Which serum laboratory value is likely to be elevated for this client?
- A. Amylase
- B. Creatinine
- C. Blood urea nitrogen
- D. Bilirubin
Correct answer: D
Rationale: Bilirubin is a key serum laboratory value that is likely to be elevated in clients with jaundice. Jaundice is characterized by a yellowish discoloration of the skin and eyes due to an excess of bilirubin, a breakdown product of hemoglobin. Elevated amylase levels are associated with pancreatic conditions, not specifically jaundice. Creatinine and blood urea nitrogen are markers of kidney function and are not directly related to jaundice.
4. Oxygen at liters/min per nasal cannula PRN difficult breathing is prescribed for a client with pneumonia. Which nursing intervention is effective in preventing oxygen toxicity?
- A. Avoiding the administration of high levels of oxygen for extended periods.
- B. Administering a sedative at bedtime to slow the client's respiratory rate.
- C. Removing the nasal cannula during the night to prevent oxygen buildup.
- D. Running oxygen through a hydration source prior to administration.
Correct answer: A
Rationale: The correct answer is A: Avoiding the administration of high levels of oxygen for extended periods. Oxygen toxicity can occur when high levels of oxygen are given for a prolonged period. It is important to monitor and adjust the oxygen levels as needed to prevent toxicity. Choice B is incorrect because administering a sedative to slow the respiratory rate does not directly prevent oxygen toxicity. Choice C is incorrect as removing the nasal cannula during the night can compromise the client's oxygenation. Choice D is incorrect as running oxygen through a hydration source does not prevent oxygen toxicity; instead, it may introduce risks associated with the hydration source.
5. A client who has had three spontaneous abortions is requesting information about possible causes. The nurse's response should be based on which information?
- A. Chromosomal abnormalities are the most common cause of early spontaneous abortions
- B. Incompetent cervix can cause spontaneous abortions
- C. An infection can cause spontaneous abortions
- D. Nutritional deficiencies are the most common cause of early spontaneous abortions
Correct answer: A
Rationale: The correct answer is A: Chromosomal abnormalities are the most common cause of early spontaneous abortions. Spontaneous abortions, also known as miscarriages, often occur due to chromosomal abnormalities in the fetus. These abnormalities are a common cause of early pregnancy loss. Choice B is incorrect because an incompetent cervix typically leads to late miscarriages, not early spontaneous abortions. Choice C is incorrect as while infections can be a cause of spontaneous abortions, they are not the most common cause. Choice D is incorrect as nutritional deficiencies are not the most common cause of early spontaneous abortions.
